Abstract
Systems, methods, and software can be used to identify fracture planes in a subterranean zone. In some aspects, data representing locations of microseismic events associated with a subterranean zone are received. Fracture plane parameters are calculated from the locations of the microseismic events. The fracture plane parameters are calculated based on a sum of weighted terms, and each of the weighted terms includes a weighting factor that decreases with a distance between at least one of the microseismic events and a fracture plane defined by the fracture plane parameters.
Claims28
A computer-implemented method for analyzing microseismic data, the method comprising:
- receiving data representing locations of a plurality of microseismic events associated with a fracture treatment of a subterranean zone;
- and
- calculating, by data processing apparatus, a fracture plane parameter from the locations of the plurality of microseismic events, the fracture plane parameter calculated based on a sum of weighted terms, each of the weighted terms including a weighting factor that decreases with a distance between at least one of the microseismic events and a fracture plane defined by the fracture plane parameter.
A non-transitory computer-readable medium encoded with instructions that, when executed by data processing apparatus, perform operations comprising:
- receiving data representing locations of a plurality of microseismic events associated with a fracture treatment of a subterranean zone;
- and
- calculating a fracture plane parameter from the locations of the plurality of microseismic events, the fracture plane parameter calculated based on a sum of weighted terms, each of the weighted terms including a weighting factor that decreases with a distance between at least one of the microseismic events and a fracture plane defined by the fracture plane parameter.
A system comprising:
- a computer-readable medium that stores data representing locations of a plurality of microseismic events associated with a fracture treatment of a subterranean zone;
- and
- data processing apparatus operable to calculate a fracture plane parameter from the locations of the plurality of microseismic events, the fracture plane parameter calculated based on a sum of weighted terms, each of the weighted terms including a weighting factor that decreases with a distance between at least one of the microseismic events and a fracture plane defined by the fracture plane parameter.
